A person with astigmatism will complain of blurred vision of both near and distance objects. It is caused by an irregular shape of either the cornea or the lens of the eye. Normally it is spherical in nature like a soccer ball, but an eye with astigmatism is often described as being almond or rugby ball shaped. It can occur in combination with long or short-sightedness.
Astigmatism can make things uncomfortable and difficult to focus on and may cause headaches, poor concentration and tiredness, especially when concentrating on a particular task. Glasses can be prescribed to make the vision clearer and reduce symptoms.
